Hello,
I am trying to build an android application to gather sensor information from my estimote beacons. I am new to this technology but not new to android. Could someone help me in creating this application. I am also trying to claim a beacon which was given to me but I keep getting the “Claim failed due to server error. Please try after few minutes”. Also, what are the plugins required in android studio to create an app? Are there any templates already available which I could use?
Thanks.
Hi @saurabhrao,
first, you have to know what kind of beacon you have: Proximity beacon, Location beacon or Sticker beacon? You can watch for the Estimote web-site. To be sure, note that the Sticker beacon is the small one, the Proximity beacon is the “basic” one and the Location beacon the stronger one. It will inform you with the data you can have from your beacon:
To build an Android app’ using the Estimote technology, you have to follow the instructions given in the Estimote Android SDK GitHub page:
You have some templates in the GitHub (here), but it’s more convenient to follow the on-line guide. Follow the changelog file if you’re blocked with old classes/methods.
I can’t help you with the claim issue, need here an Estimote staff member.
Hi @Ximun,
I have question regarding gathering telemetry information. I am getting an incompatible type error while following the tutorial online.
I have attached a snippet of the code. he startTelemetry function is type void and we are trying to put it in to a string. Could you please let me know what the solution could be?
Hey,
looking at your code, I can’t see any listener put to the BeaconManager instance:
this.beaconManager.setTelemetryListener(new BeaconManager.TelemetryListener {
public void onTelemetriesFound(List<EstimoteTelemetry> telemetries) {
// Retrieve your sensor datas here.
}
});
Try not to check the return value (because it’s void):
@Override
public void onServiceReady() {
this.beaconManager.startTelemetryDiscovery();
}
And to stop the discovery:
this.beaconManager.stopTelemetryDiscovery();
Also, why have you 2 onCreate() methods? I think there is only one onCreate() method overrided, this one:
protected void onCreate(Bundle savedInstanceState);
The Oncreate function is a part of the previous tutorial for ranging of the beacons. Should i remove that? How will it still connect? Attaching a screenshot. Appreciate the help.
I don’t understand why you have 2 onCreate() methods with:
I was following this tutorial:-
http://developer.estimote.com/android/tutorial/part-3-ranging-beacons/
and now I’m continuing with this one:-
http://developer.estimote.com/sensors/estimote-telemetry/
Should both of them be on separate Java classes?
OK ^^
Yes I think you should do 2 projects (2 applications). If you know how to code in Java Android, you can put an Activity for each process.
public class MyTelemetryListener extends AppCOmpatActivity {
private BeaconManager beaconManager;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.setContentView(R.id.activity_main);
this.beaconManager = new BeaconManager(this);
this.beaconManager.setTelemetryListener(new BeaconManager.TelemetryListener {
@Override
public void onTelemetriesFound(List<EstimoteTelemetry> telemetries) {
for (EstimoteTelemetry t : telemetries) {
Log.d("TELEMETRY", "beaconID: " + t.deviceId + "temperature: " + t.temperature + "°C.");
}
}
});
}
@Override
protected void onResume() {
super.onResume();
this.beaconManager.connect(new BeaconManager.ServiceReadyCallback {
@Override
public void onServiceReady() {
beaconManager.startTelemetryDiscovery();
}
}
}
@Override
protected void onPause() {
this.beaconManager.stopTelemetryDiscovery();
super.onPause();
}
@Override
protected void onDestroy() {
this.beaconManager.disconnect();
super.onDestroy();
}
}
Hey,
the initialize() method signature is:
public static void initialize(android.content.Context, java.lang.String, java.lang.String)
so we can’t verify…
1.0.1 version.Hey,
are you calling initialize() in your application or activity onCreate() method?
I’m calling it in the application class not the main_activity. Where do I need to call it?
Calling it in the MyApplication.java class file is what you need to do:
public class MyApplication extends Application {
private final static String APP_ID = <your app ID>;
private final static String APP_TOKEN = <your app token>;
@Override
public void onCreate() {
super.onCreate();
EstimoteSDK.initialize(this, APP_ID, APP_TOKEN);
}
}
Hi,
I tried both with and without quotes. It doesn’t like it
No, it’s like:
private final static String APP_ID = "beacon-app2-bn1";
Did you write in your application’s onCreate() method:
EstimoteSDK.initialize(this.getApplicationContext(), APP_ID, APP_TOKEN);
